Abstract
A hand held compressed air power tool is provided with a handle that can axially rotate about an orthogonal axis perpendicular to the tool housing. Thus, the handle can rotate independently of the motor housing thereby allowing the handle to point in a different direction other than toward the point of impact. The tool utilizes a rotational coupling system that allows the handle to rotate while also allowing compressed air to be fed into, and exhausted out of, the tool via the base of the handle.
Claims23
A hand power tool comprising:
- a housing including a motor, said motor being rotatable about a longitudinal axis;
- and
- a handle mounted to said housing on an axis perpendicular to and intersecting said longitudinal axis, said handle including a trigger mounted thereto, said handle and said trigger being rotatable about said perpendicular axis.
A hand fluid driven power tool comprising:
- a motor housing including a motor which rotates axially about a longitudinal axis, a motor housing intake port, and a motor housing exhaust port;
- a handle positioned on said motor housing along an axis perpendicular to and intersecting said longitudinal axis, said handle comprising a handle inlet port and a handle outlet port;
- and
- a rotational coupling system connecting said handle to said motor housing, said coupling system including means for rotation of said handle, including said handle inlet port and outlet port, about said perpendicular axis.
A hand held power tool comprising:
- a tool housing comprising a first end and a second end, said first end adaptable for attaching a rotational tool device;
- a handle extending outward from said tool housing having a pneumatic passage therethrough;
- and
- a pneumatic seal positioned between said tool housing and said handle;
- and
- a rotational coupling system rotatably connecting said handle to said tool housing such that said handle can rotate about an axis which is perpendicular to and intersecting a longitudinal axis of said tool housing.
